UPN 160 — Dimensions, Weight & Section Properties
UPN channel per DIN 1026-1
UPN 160 is a UPN channel per DIN 1026-1, 160 mm tall and 65 mm wide, weighing 18.8 kg per meter. All dimensions and section properties below are the standard published values used in structural design across Europe.
Typical uses: floor beams, columns, frames, and general steel construction. For a quick strength check, use the deflection example below or open the beam calculator with your own span and load.

Deflection example
A simply supported UPN 160 spanning 3 m with a 10 kN point load at midspan deflects 2.9 mm (E = 210 GPa, Ix = 925 cm⁴). The L/360 serviceability limit for this span is 8.3 mm — the profile passes this quick check.

Frequently Asked Questions
How much does UPN 160 weigh?
UPN 160 weighs 18.8 kg per meter. A standard 6 m bar weighs 112.8 kg and a 12 m bar 225.6 kg. The weight follows from the cross-section area of 24 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of UPN 160?
UPN 160 is 160 mm tall and 65 mm wide, with a web thickness of 7.5 mm, a flange thickness of 10.5 mm, and a root radius of 10.5 mm, per DIN 1026-1.
What is the moment of inertia of UPN 160?
About the strong axis, Ix = 925 cm⁴ with a section modulus Wx = 116 cm³. About the weak axis, Iy = 85.3 cm⁴ and Wy = 18.3 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
UPN 160 or UPN 180 — what does one size up change?
UPN 180 is about 17% heavier (22 vs 18.8 kg/m) but about 46% stiffer (Ix 1,350 vs 925 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
